Free 7 minute online countdown timer with alarm. Use for the 7-minute workout, cooking tasks, timed exercises, and productivity intervals. No install.
Custom Duration
Seven minutes gained global fitness fame in 2013 when a study published in the American College of Sports Medicine's Health & Fitness Journal described a high-intensity circuit training protocol — 12 exercises, 30 seconds each with 10-second transitions — that could deliver meaningful cardiovascular and muscular benefits in a total of 7 minutes. The study spawned countless apps and a lasting cultural association between 7 minutes and efficient exercise. Beyond fitness, 7 minutes appears as a practical interval in several contexts. When reheating a full meal in a microwave, 7 minutes is often the total time across multiple short bursts with stirring in between. In presentations and pitches, the 7-minute talk has become popular as a structure that forces ruthless prioritization — long enough to develop one idea with nuance, short enough to hold an audience's full attention. The format was popularized by conference series like Ignite and 7x7. For productivity, 7-minute work blocks can help overcome the activation energy problem — the resistance to starting a difficult task. Committing to just 7 minutes of focused work on something you've been avoiding is low-stakes enough to begin, and beginning is usually the hardest part.

Frequently Asked Questions
What is the 7-minute workout?
The 7-minute workout is a high-intensity circuit of 12 bodyweight exercises — including jumping jacks, push-ups, squats, plank, and more — each done for 30 seconds with 10 seconds of rest. The full circuit takes exactly 7 minutes and can be repeated for longer sessions.
Is 7 minutes of exercise actually effective?
Research shows that high-intensity intervals of 7 minutes can meaningfully improve cardiovascular fitness and muscular endurance, especially for sedentary individuals. It's not a replacement for longer training but is significantly better than doing nothing, and the low time commitment improves adherence.
How can I use this timer for a 7-minute presentation?
Start the timer as you begin speaking. The alarm at 7 minutes signals the end of your allotted time. For practice, run through your slides once with the timer running to identify which sections to cut.
Does the timer work when my phone screen is off?
The timer continues running when you switch apps or lock the screen, but the alarm requires the browser's audio context to be active. On iOS, keep the browser in the foreground or use the silent mode off to ensure the alarm fires.
